摘要:
研究了山西地堑系1038年定襄地震、1303年洪洞地震和1695年临汾地震中形成的大量地震重力地貌。这些重力地貌具有成群分布，同时性的特点，并有在非地震条件下难于发生的特殊滑坡现象。地震重力过程作为一种土壤侵蚀的方式，具有分布集中，强度大，历时短，难防范，破坏性大的特点，同时，地震重力地貌过程的堆积物进入河流系统，增强了水流的侵蚀能力。
Abstract:
The Shanxi Graben System is composed of a series of basins,which arranged in a s-shaped curve over a distance of 1 200 km from the north to the south.Since 231 AD,twenty earthquakes of a magnitude equal to or larger than 6 have occurred,including one of M=8,five of M=7～7.9,and 14 of M=6～6.9.According to the Chinese historical records,these earthquakes have induced a lot of landslides.The coseismic landslides of Dingxiang(M=7,in 1038),Hongdong(M=8,in 1303) and Linfen(M=8,in 1695) earthquakes are studied here.According to Lichen measurements,the 75%～85% landslides are synchronous.The coseismic landsliding is a way of soil erosion in the Shanxi Graben System.The deposits of landsliding also intensify the water erosion along rivers.
